NFL Preseason 2012: Report-Card Grades for Every NFL Roster

I don't care how great an NFL coaching staff is; if they don't have some talent on the roster, it's going to be a long year.

That's why I examined every roster: to see which teams have the talent to make some noise and which don't. I wanted to see which teams had the most elite talent, which teams had the biggest holes to fill and which had enough quality depth to withstand an injury or two.

The offensive line is a potential point of weakness, especially since Will Beatty's back is still giving him problems.

There is quality depth on both sides of the ball. They may need it, as Nicks and Canty might not be fully healthy for the start of the season and cornerback Terrell Thomas is definitely going to miss some games.

The position of concern is obviously quarterback. The starter, Mark Sanchez, makes too many mental mistakes, and the backup, Tim Tebow, is too erratic throwing the ball. But Tebow has a huge following, so there will be a controversy brewing at some point.

There also are depth issues at right tackle, wide receiver and tight end.

Rookie outside linebacker Melvin Ingram will start eventually and looks ready to make an immediate impact as a pass-rusher.

The Chargers took a hit when starting running back Ryan Mathews broke his collarbone in their first preseason game, and wide receiver Vincent Brown broke his ankle over the weekend in the second preseason game.

Sam Bradford will have to show the Rams this year that he is the franchise quarterback they thought he was when they selected him No. 1 overall in 2010. There are obvious holes at wide receiver and tight end, and the Rams made no effort to upgrade those positions, which will make it harder for Bradford to make that happen.
